Measuring AC voltage
The AC voltage measurement function has the following features:
– Five ranges to select: 100 mVrms, 1 Vrms, 10 Vrms, 100 Vrms, and 250 Vrms,
– Measures the AC-coupled true RMS.
– Measures within the stipulated accuracy at a crest factor of a maximum of 5:1
– Input impedance is 1 MΩ ± 2% in parallel with less than 120 pF capacitance on
Make the connection as shown below.
Keysight Measurement Manager operation
Select the ACV function and desired range. A suitable range should be selected to
give the best measurement resolution. The reading is displayed and updated
continuously.
